Nginx - 504 Gateway Time-out - upstream timed out - Connection timed out

Dobrý den,

mám další problém s webserver Nginx na linux serveru. Při dlouhém importu mám chybu 504 Gateway Time-out. Prosím někoho o pomoc. Díky

CHYBA
------------------------
504 Gateway Time-out
nginx/1.18.0 (Ubuntu)

tail /var/log/nginx/error.log

ODPOVĚĎ

Dobrý den,

upravte konfiguraci Nginx + PHP - je třeba navýšit limity, zkuste navýšit v php.ini max_execution_time a max_input_time, dále v nginx virtualhostu fastcgi_read_timeout takto:

vim /etc/php/7.4/fpm/php.ini

.................
; Maximum execution time of each script, in seconds
; http://php.net/max-execution-time
; Note: This directive is hardcoded to 0 for the CLI SAPI
max_execution_time = 300

; Maximum amount of time each script may spend parsing request data. It's a good
; idea to limit this time on productions servers in order to eliminate unexpectedly
; long running scripts.
; Note: This directive is hardcoded to -1 for the CLI SAPI
; Default Value: -1 (Unlimited)
; Development Value: 60 (60 seconds)
; Production Value: 60 (60 seconds)
; http://php.net/max-input-time
max_input_time = 180
....................

vim /etc/nginx/sites-available/virtualhost.conf

server {
.................
fastcgi_buffers 16 32k;
fastcgi_buffer_size 64k;
fastcgi_busy_buffers_size 64k;
proxy_buffer_size 128k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;
fastcgi_read_timeout 180;
....................

systemctl reload nginx;systemctl restart php7.4-fpm
